Arbiter rules in favor of Jeremy Piven

Actor did not breach 'Speed-the-Plow' contract

NEW YORK -- Score one for Jeremy Piven.

A professional arbiter has ruled Piven did not his breach his contract with the Broadway producers of "Speed-the-Plow" when the actor abruptly left the revival of the David Mamet play last December.

At the time, Piven's doctor said Piven was suffering from mercury poisoning after eating too much fish.

Piven says in a statement that he's pleased with the outcome and says he's been vindicated.

The producers, meanwhile, expressed disappointment. They say they respect the decision, but strongly disagree with it.

The actor is also known for playing Hollywood agent Ari on "Entourage."
